[chef] Allocating an Elastic IP with aws_eip_address

[Jos Backus < >]

Hi,

Given a machine named “foo”, I am trying to create a new Elastic IP address using the following recipe:

name = “foo"

aws_eip_address "#{name}-eip" do

  machine name

  action :create

end

I’m getting the following exception and stacktrace:

IPAddr::AddressFamilyError: address family must be specified

For some reason, coerce on the resource is called with nil as the value, so the code calls IPAddr.new(nil), presumably because I didn’t specify a public_ip attribute. If I specify that, it works, but obviously I don’t want to have to do that - I want the resource to create the elastic IP itself, using the create action.

How is this supposed to work? Is it a bug?
